Has anybody built a sealed room with Panda/Orca paper

Just curious if it’s feasible. I think i seen someone who done it by just making sure it’s tight to the studs and it was stapled and then taped over with white or reflective tape. Not sure how it work out but they did use an central ac

yes its feasible
not sure it's necessary though

I've made partitioned areas or close off tents with Orca Paper. They did the job but they weren't sealed or tight or anything.

Orca paper is good, it's heavy duty and can be used over and over.

A few cheap adjustable clamps make building the frame way, way easier.
